I.
Replace and tighten body stud nuts (27).
J.
Replace packing flange stud nuts (94) and finger
tighten only.
K.
Slide the lever (34) on the shaft (19) toward the
valve and tighten lever capscrew (49).
L.
Pull the lever and shaft toward the bearing (8) in
the yoke.
M.
Loosen lever capscrew (49) and slide lever (34)
so it will shoulder against the shaft bearing (8)
and tighten capscrew (49).
Note: if the actuator cylinder (38) has been
removed proceed to step N. If it has not, proceed
to section 11. on actuator stem adjustment.
N.
Determine the desired actuator action and
replace actuator cylinder (38) on the yoke (33)
and secure in place with four capscrews (36) and
lockwashers (37).
O.
Proceed to section 11. on actuator stem
adjustment.
10.3 HANDWHEEL REASSEMBLY
A.
Place the valve so the position cover (11) is up.
B.
Remove Truac ring (50) and handwheel washer
(51) from the handwheel powerscrew.
C.
Insert handwheel powerscrew with lock (52) in
place into the appropriate hole in the yoke and
screw in clockwise.
D.
Replace the washer (51) and Truac ring (50)
E.
Back off handwheel lightly against washer and
lock in the off position with lock (52).
F.
Replace bottom cover (11) by snapping in place.
Note: To use the handwheel, loosen the lock (52)
and turn. The handwheel can be use as a limit stop
on the valve by locking it in any position.
10.4 LIMIT STOP REASSEMBLY
Two different types of assembly for the limit stop in
function of the actuator size: see figure 9.
10.5 VALVE BODY REASSEMBLY
(Refer to figure 16)
Prior to reassembly, the valve body should be
thoroughly cleaned and the seat ring and plug may
be lapped as indicated in section 9.2. Upon
completion of the above, proceed as follows:
A.
Apply a small amount of thread lubricant to the
seat ring retainer threads and install seat ring
retainer (3) and hand tighten only.
B.
Place valve body (1) on flat surface so that the
seat is down.
C.
Coat lower guide bushing (22) with
recommended lubricant and insert into the body.
Note: Groove in the guide bushing (22) must be
towards the body center.
Refer to figure 10 for correct assembly
sequence. If the shaft (19) is the older design it
may have a circular grove, if so install the
retaining ring.
Caution: This is required to insure the shaft
(19) is shouldered on the shaft bearing (8) and
to insure free operation of the valve.
LIMIT STOP STD CAMFLEX 6" and 7"
LIMIT STOP STD CAMFLEX 4.5"
Figure 9
Lubricants and sealers are required during
reassembly. Figure 15 identifies
recommended products for certain service
conditions. Insure that any lubricant used is
compatible with service conditions.
Caution: Do not tighten the seat ring retainer
to torque specification at this time.
